Effect of a High-IntensityInterval Training Session on Post-Exercise Hypotension andAutonomic Cardiac Activity in Hypertensive Ederly Subjects.JEPonline 2018;21(3):58-70. Factors that influence themagnitude of post-exercise hypotension (PEH) have beenthe subject of numerous studies, but there are no establishedarguments as to the hypotensive effect of a High IntensityInterval Training session (HIIT). The purpose of the presentstudy was to evaluate the influence of an HIIT session on themagnitude of PEH and Cardiac Autonomic Activity (CAA) ofhypertensive elderly. Fifteen hypertensive patients (65.1 ±5.37 yrs) performed two procedures on the cycle ergometeron non-consecutive days; HIIT with 4 sprints of 4 min with anintensity of 85 to 90% of Heart Rate Reserve (HRR) andintervals of 2 min to 50% of the HRR; and ContinuousAerobic Exercise (CAE) of 45 min at an intensity of 60 to80% of the HRR. Both the blood pressure measurement andautonomic activity recording were performed in the preexerciseperiod, post-exercise and during recovery for 1 hr.Two-way ANOVA test with Bonferroni post hoc were used tocompare the inter- and intra-procedure measurements. The data were analyzed in the Graph Pad Prism version 6.0 statistical software. Systolic (PSH)and diastolic (PDH) hypotension were measured in both procedures for 1 hr. There was nosignificant difference for PDH (P=0.2947) between procedures. The autonomic balance(HF/LF) presented a reduction between the post-exercise values and the values of therecovery period in both procedures (P=0.0001). The HIIT session promoted a greaterhypotensive effect when compared to the CAE.
